Make an area chart.
Documentation: area_hollow,
inherits from area_line.
See the area hollow for details on the methods
This goes into the <head> of the page:
<script type="text/javascript" src="js/swfobject.js"></script>
<script type="text/javascript">
swfobject.embedSWF(
"open-flash-chart.swf", "my_chart",
"550", "400", "9.0.0", "expressInstall.swf",
{"data-file":"gallery/area-on-show-animation.php"} );
</script>
This writes the chart into a div with id="my_chart",
right click and view source to see it in action,
[the tutorials have more details]
gallery/area-on-show-animation.php
<?php
$data = array();
for( $i=0; $i<22; $i+=0.2 )
{
$tmp = sin($i)*1.9 + 3;
$data[] = $tmp;
}
include '../php-ofc-library/open-flash-chart.php';
$chart = new open_flash_chart();
$chart->set_title( new title( 'Area Chart' ) );
//
// Make our area chart:

$d->colour('#9C0E57')->size(3);
$area = new area();
// set the circle line width:
$area->set_width( 2 );
$area->set_default_dot_style($d);
$area->set_colour( '#C4B86A' );
$area->set_fill_colour( '#C4B86A' );
$area->set_fill_alpha( 0.7 );
$area->on_show(new line_on_show('pop-up', 2, 0.5));
$area->set_values( $data );
// add the area object to the chart:
$chart->add_element( $area );
$y_axis = new y_axis();
$y_axis->set_range( 0, 8, 2 );
$y_axis->labels = null;
$y_axis->set_offset( false );

$x_axis->labels = $data;
$x_axis->set_steps( 2 );
$x_labels = new x_axis_labels();
$x_labels->set_steps( 4 );
$x_labels->set_vertical();
// Add the X Axis Labels to the X Axis
$x_axis->set_labels( $x_labels );
$chart->add_y_axis( $y_axis );
$chart->x_axis = $x_axis;
echo $chart->toPrettyString();
